Umar and his team is the best in every.single.aspect! I had a bunch of companies come out to give a attic insulation removal and installation estimate and not only was their price the best but customer service was top notch. They are on time, efficient, careful and most importantly HONEST. The are very flexible on scheduling (I don't think they have any days off!), prompt in replying, just absolute stellar company. They did my insulation removal on Sep 1 and insulation installation on Oct 23. I was so satisfied with them that I contacted them again in January for a furnace repair! Thank you so much Umar and team. You have a customer for life and I will recommend Insulation Alliance to everyone I know! read more

I discovered this shop on Yelp after it recommended several local businesses. I had multiple quick quotes, but Umar provided the greatest response and cost, as well as a quick two-day schedule on Sunday, which is my day off, so he saved my days. His worker blew insulation through the holes he made in the walls. and expertly completed within four hours. Everything was cleaned, vacuumed, and dust cleaned after work. Umar emailed me the certificate letter so that I could show it to the City Inspector. Thank you, Umar, and your workers for being professional and responsible. You deserve to have the very best business. read more

Insulation Alliance - Holes that the insulation blown in. We've cut around the door after, per inspection request. - Insulation Installation Near Me

We were initially told by another HVAC company that we needed to replace all of the air ducts and insulation in our attic, add insulation in the rafters, and address rodent droppings in the crawl space. When Elmer came out, he took about 30 minutes to walk through the house and gave us a completely different--and much more reassuring--assessment. He identified entry points where rodents were getting into the crawl space, explained that the air ducts did not need to be replaced, and instead recommended insulating the rafters, reinsulating the attic floor, and cleaning and reinsulating the crawl space. He also suggested installing an attic fan to improve air circulation. Throughout the visit, he was straightforward, knowledgeable, and very approachable. We decided to move forward with the attic fan. Umar updated the contract promptly and even came out personally to help program the fan and connect it to my phone. Their team worked tirelessly over four days and did an excellent job. They were professional, detail-oriented, and left the house clean when they were done. We enthusiastically recommend Insulation Alliance. Thank you, Elmer, Umar, and team! ST, Redwood City read more

Insulation Alliance was quick with the estimate. Their service was excellent. They described all that was needed with pictures and documentation. The estimate was thorough, detailed and fair. Their price was good and accurate. They showed up on time, performed their duties as described and cleaned up when they finished the job. I had some slight complaints that they addressed immediately. I am pleased with their work and do recommend. read more

Insulation Alliance was one of several companies i selected to quote on my attic insulation. Umar did a thorough inspection of the attic and noted several items to address, a few holes where air flow leaked, minor rodent droppings and inadequate insulation. He was professional and experienced. He sent a complete proposal listing the work and costs which was just slightly higher than the lowest one but much more complete and had options for the insulation. The work was scheduled and completed within a week and is excellent with my heater running less and the house more comfortable. He is honest and knowledgeable and I highly recommend his company. PS. I asked for before and after photos and could see the outstanding job they did . read more

Amazing work by Insulation Alliance! They came and insulated our entire apartment in just two days. What was especially incredible was how they managed the super reduced space in our attic, making very few holes on the ceiling. These guys are truly skilled! Highly recommend their efficient and precise work. read more

Umar and team helped re-insulate our attic and convert our existing HVAC system to a 2-zone system. We had a great experience working with the team - they were prompt, efficient and gave us a reasonable price. They finished both projects in a couple of days with minimal disruption to our schedules. When he initially visited our home for an estimate, he was honest in his assessment and answered all our questions. We decided to opt for their services and recommend them for your attic and HVAC needs! read more

Great work. Did as quoted in a timely manner. Payment got lost in the mail and they were very accommodating and communicative.

I needed insulation in a garage on short notice as part of a move-in project. Insulation Alliance did a good job and it looks great too! I get compliments from everyone who sees my garage thanks to Insulation Alliance! read more

Professional on time easy to work with. Kind of pricey but not as much as some estimates we had

very communicative and professional. They helped me get my rebate. When I noted months later that they inadvertently missed one closet wall for insulation, they were very professional and came back to complete the job without any hesitation. read more

A quick job and I wasn't even present! I had my ceilings insulated and my downstairs neighbors did as well. I appreciated how they had a technician come and give a comprehensive quote, and followed up. They shared everything ahead of time and were professional. We had 900 sq. ft. insulated for $3.8K and found that the quote and pricing was fair. The only few complaints I would have: 1. When the insulators arrived they said they needed a parking space, but no one ever told me this ahead of time. We ended up scrambling and asking our neighbor if we can use their space 2. After the insulators left, some of the furniture was left in weird positions and I spent 1 hr fixing everything 3. I wish I knew the level of severity about the holes in the ceiling, which were pretty unsightly. It's been a hassle trying to find a painter to cover it up. read more

I'm the type of person who has a spreadsheet for everything. My spreadsheet for insulation and sealing for my 1890s Victorian was comprehensive, looking at review counts, ratings, years in business, licenses, BBB, Google, Yelp - you name it. In the end, I shortlisted the top five companies, Insulation Alliance being one of them. After capturing all the quotes Insulation Alliance was right in the middle of the pack in terms of pricing, but it was clear they were ahead of the others: -Clear communication both via email and phone calls -Responsive to inquiries and changes, even allowing me to select which specific model fan I wanted in my attic -Spent the time to explain the tradeoffs of different approaches On the day of, the crew showed up on time and made short order of our two attic spaces, sealing both, putting blown in cellulose in one and fiberclass in the roof of another, and installing a temperature controlled Smart attic fan. The crew put down protective floor covering, plastic sheeting and cleaned up after themselves. They were incredibly responsive to feedback and made the process a breeze. I'd consider them for any future insulation needs. read more

They worked super hard and finished it all in a single day - all quality. I am happy and its all taken care off. Well done Insulation alliance! read more

I'm updating a 1 to a 5 based on El and Umar going above and beyond without questioning to make a difficult situation right. Umar came and took out a 10x20 section of the insulation where unfortunately a rat had been trapped. We coordinated with a trapper and ensured the rodent was out and then the team came back and promptly reinstalled new insulation and a challenging set of mesh wire to secure the insulation from future rodents. Really great work in the end, and exceptional ownership. read more

We had a fantastic experience with Umar and his crew for our recent attic insulation project. Out of the 6 companies we consulted, they stood out immediately--not only for their thoroughness but for offering valuable insights others completely overlooked or didn't bother to mention due to lower profit margin (cellose roughly 10% more efficient than batt or you want to insulate the attic hatch itself!). Installation crew of 2 treated our home with exceptional care, using plastic barriers and floor coverings to keep everything spotless. I also appreciate the crew accommodated my ask with enthusiasm and understanding to check in on their progress at every major process step (clean up, rodent proofing/air sealing/sanitization before they installed the new insulation). They do not cut corners. The work was top-notch, and the professionalism unmatched. Best of all, Umar delivered on desired outcomes - significant improvement in temperature dynamics in just the first night after insulation! He was also easiest to work at every interaction, from initial outreach to follow ups when I peppered him with questions :) Thanks again Umar. Highly recommend to friends and neighbors without hesitation! read more

I had five different companies come out to do estimates on insulating our attic. I chose insulation Alliance for a number of reasons. They were extremely professional, explained their entire process, and provided a very detailed estimate with pictures of our existing insulation. Their pricing was extremely fair and competitive, great communication, they did not pressure us at all. As well they offered a company BayRen Home+ that provides energy rebates for qualifying work, which this project qualified for. Their crew came on time, worked extremely efficiently, did great work, and left our home spotless. I would highly recommend them for your insulation needs! read more

Hired Umar to do a vaulted ceiling insulation. Very knowledgeble, the ceiling job came out so well and room stays cool. minor concern while drywall finishing but Umar worked to close this problem and understood our concerns, Will hire them back for the xterior wall projects at a later date. Highly recommend Umar! read more

You cannot go wrong with Umar and his team at Insulation Alliance. From the start, Umar is professional, thorough, and is a thought partner for what we should consider in terms of insulating our 1960s house. He provided a detailed proposal to ensure accuracy and alignment on job details and included a few additional ideas I told him I wanted to consider but wasn't sure about. His pricing is very fair. When I gave my final feedback on the proposal, he generated a new one that I signed. His team works extremely diligently, quietly, cleanly. Although communication was challenging, they knew what to do and got on it. They worked until the job was done and cleaned up well afterwards. They did an excellent job and their work was really neat and tidy. I'm thrilled. There was one hiccup where the installers misunderstood where to put the insulation so they put it a storage area that didn't need it. Umar left it there at no charge, no argument, no fuss. These are stand up people. Hard-working, honest, and I'd hire them again. Very happy read more

Umar was quick to return my phone call & visit the site within a day. Estimate came quickly after our meeting. Installing ceiling soundproofing-mineral insulation, joist drywall layers and drywall laters with a resilient channeled ceiling. Green glue everywhere. Excellent job; workers were on site every day for a week. These guys were quick, thorough and professional. Umar knew exactly what needed to be done; I knew after he sent the diagram with the estimate. Will definitely use them again. read more

If I could give this company 10 stars, I would! From the outset, they were flexible and very accommodating with scheduling. Their price was half what we got quoted elsewhere. Their workers were extremely prompt, professional, respectful and efficient. They covered everything in my house with plastic down to the smallest detail and got the job done very quickly while also doing so very thoroughly. The painting was also excellent. We are very pleased with our entire experience. I would highly, highly recommend you go with this company for all of your insulation needs. read more

El and Ulmar came by to provide a quote. After that everything went smoothly. The team showed up as scheduled and did a great clean job. Cleaned up after the work was completed. read more

The owner, Umar, really came through! We spoke on the phone regarding the misaligned outlet, and he immediately came by to look at it firsthand. I explained to him my situation. It was Friday and I told him I needed to have the room ready to go by Monday so I could return to work (I work from home). He was very sympathetic to my situation and arranged for his crew to come out on Saturday. His crew came out (on a weekend) and fixed the issue in about an hour. Everything is perfect now! The way Umar resolved the situation speaks volumes about his character. He truly cares about his customers and the quality of work his company provides. Even something as small as a misaligned electrical outlet was serious enough for Umar to take care of right away. I recommend Insulation Alliance to anyone with insulation or soundproofing needs. read more

Gave us a great quote for insulation on our floors and walls and was honest about the headache wall insulation would be given we have lath and plaster. read more

We got the insulation installed for both attic and crawl space by Insulation alliance. We had a positive experience overall and they were able to finish the work pretty fast. They were also very patient in explaining and answering questions. Their quote was also very competitive compared to other companies. They also took care of Bayren rebate application and I received my rebate check as well. I would definitely recommend Insulation alliance for any insulation related work. read more

El and Umar are serious pros. They're kind, patient, and it's clearly important to them that they do high-quality work. At our home they advised me on the best way to do sound insulation for a wall between two bedrooms -- which absolutely checked out against a bunch of online research I did -- and they also arranged for drywall texturing and painting. When Umar came by at the end of our job to double check that everything went well, we found a couple places where paint had bubbled due to the recent rains' moisture in the air; he immediately arranged to have this fixed. We're very happy with the work El and Umar did and wouldn't hesitate to work with them again and again! read more

Umar and the entire Insulation Alliance team were a joy to deal with. They were on time, on budget, thorough and attentive. Communication was up front and clear, and the price was extremely competitive. The team immediately fixed all of the (minor) issues that I pointed out, and the insulation and sealing had an immediate and major effect on the energy efficiency of our HVAC. The BayREN rebate came through as promised, too. Attic and crawlspace insulation is a tough job, and I am very grateful to the Insulation Alliance team for taking care of it for us in a professional manner. read more

Attic and crawlspace cleaning exceeded my expectations with their respectful and professional service from Umar and team. They just did their thing, and it was awesome. Clear, no BS communication. I appreciate the commitment to quality without overpromising. I highly recommend them for their reliability and dedication to a job well done. You have a repeat customer. read more

I initially contracted with Insulation Alliance to insulate a couple of walls and a portion of the attic space. Since there was way more rat feces than expected, the entire attic was cleaned, pest proofed, disinfected and multiple layers of R25 were put down. I had a radiant barrier installed on the part of the roof facing south. In addition, they air sealed the openings in the attic floor. The crew was timely and they worked hard. The operation is clean -- painters plastic is wrapped around the areas they are working to keep the dust and fiberglass out. They removed all old insulation and trash. The entire operation took a few days. The only thing I would have done differently would have been to air seal the top plates in the attic when it was clean. Overall, the crew worked hard and fast. They're a good crew to insulate your residence. read more

I had the pleasure of working with Insulation Alliances for BayRen Rebate Eligible insulation of my house in Oakland hills earlier this month. From my very first interaction with the co-owner Eldar, till the end of the project, entire experience was seamless. We ended up insulating my Attic, Walls and the Crawl Space. It is still little early to feel the full impact (it's summer now), but i feel the difference. Eldar showcased extensive knowledge and expertise in insulation during our initial consultation. They carefully assessed my home's insulation needs and explained the available options in detail. Their willingness to listen to my concerns and address my questions immediately demonstrated their commitment to customer satisfaction. Insulation Alliance team was skilled and efficient, arriving on time and ensuring the work area remained clean and protected.

Insulation Alliance - Insulation Installation Near Me

3 years ago we had our insulation "re-done" but it was poorly done and caused us a lot of issues. I shopped around for licensed contractors and received a total of 5 quotes. Insulation Alliance offered to re-do the entire attic plus air seal the attic for a little more than the other vendors quoted me to simply "patch" up the missed areas from the previous work. They also sanitized the attic before installing the new insulation which was a huge plus for me. I was supper impressed with the work done, from the set up, to the insulation to the cleanup. They completely blocked off the entry way all the way to the hallway where the attic entrance is located. I could barely hear the workers in the attic so I could tell they were up there with caution, unlike the previous contractor that caused cracks on our ceiling. At the end, they encouraged me to go up to check out the work. The clean up was immaculate! They vacuumed any residue that was left behind inside the house, which was very little. But the impressive part was that they vacuumed my porch, walkway, sidewalk and the STREET!!!!! It's as if no one was in here! Very impressed and pleased with the work. I would highly recommend them! read more

I moved into a house without wall insulation. Insulation Alliance came and provided me a range of services to help me make a decision of what needed to be done. There scheduling worked out perfectly for us and we went ahead with them! On the day they arrived on time with a team of 3 people and got the entire project done, and they did a great job cleaning up as well! read more

El and Umar were very professional. It took me 2 months to make a decision about which company to hire. There were 6 contractors that I interviewed. Insulation Alliance came out the winner. They were on time, they laid plastic on my floors. They took out all the old insulation, they sanitized, they sealed the opening where the racoons were coming in. They used R44 which is very thick. It's been 2 weeks since they did the work. Already I can see the difference in the warmth of my home. You will not be disappointed. read more

I recently purchased a house in foggy Midtown Terrace. After noticing a pretty big humidity problem in my downstairs bedroom (humidity constantly in the 80s), I did some research and confirmed the previous owners didn't have much insulation in the walls or attic. So I contacted a few insulation companies and Insulation Alliance had one of the lower quotes + I was impressed with Eldar's first visit and what he pointed out that others missed. On the day of my appointment, the crew did arrive 2 hours after the original slot and the machine to blow in insulation broke down for 30 minutes. But the 3 men crew worked quickly to finish the job including cleaning up both inside and outside. The new insulation in the attic ended up pressing down on a few of my existing recessed ceiling lights - after I pointed them out, the crew did a good job mitigating including repairing a small scratch in the ceiling caused by their tape. It's been only a few days but I'm already noticing a big difference in my downstairs humidity and upstairs temperature regulation. I would take 0.5 star off for their late arrival and small impact to my ceiling lights, but the work was good and I would def recommend these guys. read more

A quick but thorough visit for an initial quote was followed up fast with a appointment.

Insulation Alliance - Blown-in loft insulation - Insulation Installation Near Me

We had attic insulation replaced last week, after having our roof shingles replaced. Almost 2000 square feet, in Fremont. The whole experience was smooth, professional, high quality, and for a very good price. They arrived for giving a quote just the day after I contacted them via Yelp, and the work was scheduled for the following week. The whole job took just one day, on schedule, and the work was very professional, and their workers were very courteous. We bought them lunch and tipped them when the work was done. Highly recommend. read more

Umar and his team did a great job to replace the insulation at my house. Their price is very competitive and Umar explained the process very well. Scheduling and communication went smoothly. The job was completed within a day. They removed the insulation, sanitize the attic, seal all the gaps and cover the recessed light cans. The crew also did a great job to cover the area and clean up afterward. One problem that came up was the crack in the ceiling that I noticed after the job was completed. The crew handled my complain appropriately and positively. The next day, Umar immediately came to inspect the issue himself and gave a reasonable explanation of what might have happened with the condition of the joist. Even though it's not their responsibility, Umar went above and beyond to send someone immediately to fix the issue on the next day. I highly recommend doing business with them. read more
